TOOL FOR SPEEADING LEAF-SPRINGS.

Specification of Letters Patent.

Patented N ov. 5, 1918.

Application filed July 31, 1918. Serial No. 24:7,599.

. the following is a specification.

The invention consists in the features and combination and arrangement of parts hereinafter described and particularly pointed out in the claim.

lln the drawings; a

Figure 1 is a side view of the tool.

Fig. 2 is a sectional view on line 22 of Fig. 1.. p

The tool consists of a rigid ll-shaped frame A, having an arm D pivoted thereto at E in one corner and pressed inwardly normally by a spring K, arranged between it and the arm. At the top of said pivoted arm 1!) there is a pointed projection it, which, in cooperation with a pointed projection Gr on the arm H of the frame acts as wedge means to separate the leaves of the spring L, so that lubricant can be inserted. At the top of the arm 11) there is also a thumb-piece J, which is used to retract arm D from its normal position toward arm B against the power of the spring K, in order to set the tool in place on the spring be fore forcing the leaves apart. By the power of screw '0, which has a suitable handle, and which meshes with screw-threads in the arm B the arm 11) is forced forward, thus Copier or thin patent may he obtained for five cents each, by addressing the Gommisaioncr pressing the leaves of the spring L apart by causing the projections F, G to approach each other. i

lit will be seen that the tool readily can be placed in position and left there while be ing operated without requirin the operator to hold it in position durlng the time that the power screw is being turned.

In removing the tool the screw is run back, in its seat in the bracket arm, a sumcient distance to allow the arm D to be retracted by hand, but during the time that the screw is being turned back the tool will maintain its position on the spring because of the spring K keeping the arm D pressed inward. Complete release will result from the operator withdrawin the arm D by hand against the power 0 the spring K.

What I claim is: p A tool for separating the leaves of springs comprising a rigid frame of lJ-shape, an arm pivoted at the base thereof, and extending up within the arms of the frame, a spring between the pivoted arm and the adjacent rigid arm to force the pivoted arm normally inward, a screw mounted in the rigid arm and adapted to bear on the back of the pivoted arm, a handle to operate the screw and points on the pivoted arm and one of the rigid arms to enter between the leaves.

In testimony whereof I afix my signature.
